Elon Musk appeared on Thursday night at The Game Awards, an awards show for the video-game industry and one of the biggest events of the year for gaming culture.

The camera found Musk in the crowd following a performance by Grimes, the award-winning pop star who's been in a relationship with Musk since 2018. Grimes debuted a song, "4AEM," which later was released on streaming services.

Grimes' performance, which featured intense CGI visuals and special effects, had a "Cyberpunk 2077" theme. The game, set to be released in April, will feature music by Grimes, and she'll also voice a character, a pop artist named Lizzy Wizzy.

Grimes' performance was announced in advance, and many people predicted that Musk would accompany her in some way.

Musk is an avid gamer and a big fan of games like "Overwatch" and "Mass Effect" that feature futuristic aesthetics and combat. "Cyberpunk 2077" definitely falls into this category to the point that Musk has even hinted at putting Tesla's new Cybertruck in it.

This was Musk and Grimes' only appearance at The Game Awards.
